The Washington Redskins endured a number of injuries in their 30-13 blowout loss to the Los Angeles Chargers, which also impacted Redskins Coach Jay Gruden’s aggressiveness late in the game.

Gruden said Monday that outside linebacker Chris Carter will need surgery after suffering a fractured fibula. Carter, a Los Angeles native, suffered the injury while on punt coverage and was carted off the field in the fourth quarter.

Inside linebacker Zach Brown had an MRI exam on his foot Monday, though the team was awaiting the results as of Monday afternoon. Brown entered the game with a hamstring and Achilles’ injuries, and he left the game on crutches and with a walking boot on his right foot.

“We’ll just have to wait and see,” Gruden said. “With him limping around here, [Martrell] Spaight will have to get some more [reps] and Josh Harvey-Clemons will have to step up his game there too if [Brown] can’t go. Add another to the list of questionable guys.”

Running back Byron Marshall will be day-to-day following a hamstring injury that occurred while fielding a kickoff in the first quarter. Marshall stumbled on the field while tracking the ball and grabbed his right leg after kneeling for a touchback. Running back Samaje Perine (illness) and wide receiver Ryan Grant (ankle) had also left the game with injuries, while the Redskins opted to sideline Trent Williams (knee) during the fourth quarter.

It left Washington’s offense with just one healthy back, LeShun Daniels, three available wide receivers, Josh Doctson, Jamison Crowder and Brian Quick, and a backup at left tackle, Ty Nsekhe. The injuries were a significant reason behind Gruden’s decision to not attempt a two-point conversion or an onside kick following cornerback Bashaud Breeland’s interception returned for a touchdown with 2:36 left. Gruden elected to kick the extra point, making it 30-13, and bring his kickoff unit on the field.

“I thought about [going for two] for a little bit, but I didn’t think it was a realistic chain of events that would have to occur to be honest with you,” Gruden said. “With the situations that we had offensively and Trent Williams out, we were down to one [running] back, Ryan Grant was banged up with his ankle and down to three to receivers and Josh [Doctson] was a little bit banged up, I just wanted to make sure I got out of that game with enough healthy bodies. I didn’t want to risk any more [injuries], especially with having to get two onside kicks, two two-point conversions with two minutes to go. I wanted to get out of this game, get back on the plane and get ready for Arizona.”
